Going to make the jump to 4G soon and it's good to hear Verizon is the fastest since they're my carrier.
I gotta tell you 3G here in Columbus, OH for me has been in a constant decline since i got my Droid 2 years ago.
The last speedtest I ran this morning was, I kid you not, 84kbps down, 4kbps up. Yes that's bits!
I don't know if the phone/ROM has anything to do with it since I use Cyanogen. I'll check the wife's when I get home since she runs stock. Can't wait to switch.
